描述：JCBLLED Damp Rated High BayFEATURES & SPECIFICATIONSINTENDED USE — The Lithonia Lighting JCBL LED Highbay is the affordable LED solution for users who prefer a luminaire with the look and feel of a round form factor. The JCBL is highly configurable and delivers comfortable and uniform lighting from mounting heights up to 30ft. Gymnasiums, warehouses, packaging facilities and other industrial applications all benefit from JCBL’s highly efficient design that saves up to 57+% over traditional sources. Certain airborne contaminants can diminish the integrity of acrylic and/or polycarbonate.CONSTRUCTION — JCBL features an aluminum heat sink to maximize heat dissipation and extend the life of the luminaire by maximizing contact with the LEDs. A glass optical enclosure (IP65 rated) protects the LEDS from dust and other air contaminants. Reflector options including aluminum, prismatic acrylic and polycarbonate ship together and easily mount to the heatsink for quick installation.OPTICS — Reflector and lens options provide maximum versatility and uniformity including up to 8% uplight with reflectors alone. Conical, flat or acrylic drop lenses offer enhanced aesthetics, minimize glare at lower mounting heights and maximize uplight (13%) when paired with acrylic reflectors.ELECTRICAL — Utilizes 90°C case temperature for maximum life at high temperatures. Less than 20% THD and PF >90. Standard 6kV/3kA(120-347v), 10kV/5kA(347-480v) surge protection, tested in accordance to IEEE/ANSI standards. Input voltages include 120-277, 347-480 without the use of a step down transformer. Lumen maintenance L91 at 60,000 hours. 0-10V dimming standard for a dimming range of 100% to 10% dimming source current is 150 microA.WIRELESS NETWORKING — XPoint? Wireless technology creates a mesh network to ensure communication between fixtures, sensors and wall stations facility-wide. This option provides superior lighting management capabilities including granular control, configuration and custom grouping for increased energy savings.INSTALLATION — Mounting options include steel hook & cord or 3/4" NPT threaded hub to accommodate stem or cast hook options.LISTINGS — UL1598/C SA C22 .2 250, Buy American Act, Damp location listed.
